ADJUSTABLE BED.

Specification of Letters Patent.

Patented Aug. 25, 1914.

Application filed November 20, 1911, Serial No. 661,283. Renewed February 12, 1914. Serial No. 818,371.

To all whom it may concern:

Be it known that I, FRANK W. KRAMER, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Adjustable Beds, of which the following is a specification.

This invention relates to improvements in adjustable beds, and has for its object to provide a bed which can be collapsed into small compass and which can be raised and lowered wlthin certain limits.

A further object is to arrange a central seat or support which can-be adjusted to regulate the tension or prevent sagging of the bed springs.

A further object is to construct a bed which may readily be converted into a cot or chair. The frame work is made preferably of angle iron for economy and strength, which material also makes the article sanitary.

These and other objects are attained by the mechanism illustrated in the accompanying drawing, in which-- Figure 1 is a side elevation of the bed arranged in the form of a chair. Fig. S2 is a partial sectional elevation, showing the an iliary seat or support, in detail. Fig. 3 is a View oi. the releasing mechanism for the supporting bars for the hinged members. Fix t is a perspective detailof the mechanism for holding the bed spring" in place, in the member raised to form the back of the seat. Fig. 5 is a View of a similar derice for holding the front portion thereof in place. Fig. 6 shows a modified form of supporting bar or frame, by means of which the improvement is adapted for use on ordinary beds. Fig; Tis a detail view of a supporting brace, for the swinging members, showing the manner in which said members may be locked at any dcsiredpoint, and the Referring to the drawings in detail, 1 represents the outwardly inclined legs of the frame work, having the intermediate horizontal portion 1, the legs beingnmited by the brace :2. Each pair of legs is united to the other by the cross brace 28 held in place by. the bolts 27. Upon the portion 1, by means of bolts 26, is mounted the body 3 of the bed, having the transverse portion 3*. The vertical portions are provided with apertures 23., so that the body may be raised and lowered upon said bolts 26, to any distance desired.

At the upper end of each portion 3 is fixed a transverse bar 8 which carries at one end a pivot pin 19, and at the other a similar pin 18. Upon the pins 19 is hinged the member 7 and to the opposite end is pivoted the member 9. Each side of the swing; mg members is provided with a pivot pin 15, carrying a brace or support 16, which enters a slot 29 in its corresponding upright portion, or frame 3, and which is provided in its lower edge with a series of notches 17, for engaging the angle iron 3.

The members '7 and 9, when the device is used as a bed, will be supported in horizon tal position at 7 and 9 respectively. \Vhen the occupant desires to assume the sitting posture the member 7 is lowered by rocking the crank 24:, of the shaft 30, which carries the wings 31, upwardly against its corresponding brace 16, lifting it from its engagement, as seen at16 in Fig. 3, and allowing it to descend through its slot 2-9, over the inclined surface of the wing. When the member 7 has been lowered to the desired point the wings 31 will be dropped permitting the braces to again engage the irons 3 by means of said notches 17. The member 9 at the same time may be raised, as seen in Fig. 1, to form the back of a chair. Each member is provided near its middle point with a support or stay, such as the chain 36, having the intermediate spring 37, and secured to the body portion at 38. This stay causes the members to be brought to their upward limit gradually and prevents them from being thrust too far forward. It will be seen that the stay will be suspended loosely when the meml'ier is in horizontal or lower position and that it will be brougl'it into action only when raised a considerable distance above that point.

An additional support is provided for the braces 16, when in elevated position, in the bars 20, which are secured upon the bolts .22 in the upper portion of the body 8, and

which carry at their ends the engaging bolts 21. These bars may be transposed so as to project in the opposite direction from that shown in Fig. 1, when it is desired to support the member 7 in an elevated position, so that either end may be used as back or front. The curved portion 16 of the braces 16 allows the members l and 9 to swing, to a vertical position without binding in against the vertical supports 4 in apertures I ed 'e of the body portion 3, so as to hold the be dropped own against the body 3, as at the intervening longitudinal wires 33 and their slots; and the downwardly inclined tip 16 prevents the brace from dropping from its slots and it rests upon the wing 31 in readiness to be released by crank 24 when the member is to be lowered.

Interposed between the vertical end pieces 3 are transverse bars 14, adjustably held 10, by means of bolts The upright 4 is secured to the cross'bars (3, which in turn are supported upon the frame 3. Upon these bars-l4 are secured sprin s 11 carrying the seat 12, which is covere by the pad '13. The adjustment of the bar 14 in apertures 1O pcrmitsthe seat to be so disposed as to prevent sagging of the bed sprin and its springs and pad allow it to yie d sufficiently to be always comfortable.

As seen in Figs. 4 and 5, the wire web consists of the springs 31, secured by one end in the flanges 7 8* and 9 respectively of the angle irons 7 8 and 9, the other ends being secured in rings 32, in which are anchored the cross wires 34. Stays 35 enga ed in the bar 6 are secured 1n rings 32 above each the end members are raise zontal.

In Fig. 6 is shown a modification in which my improved device is adapted for use on the common bedstead. The rails 1 carried by brackets 39, secured on the posts 40, have formed in proper position, near their middle points suitable apertures in which are engaged the bolts which support the frames 3, which are adjustabl carried there, as in the case above describe When the bed is completely colla sed the members 7 and 9 will spring in position alon that line when above the hori- 7 and 9 and the body will be lowered on the pins 26. In this case the member 9 is shown slightly longer than member,7',but it is obvious that the relative. lengths may be varied to suit individual" Wishes.

Having thus described my invention, wlia-t I claim, is

1. In a bed comprisin a frame, an intermediate body section vertically adjustable therein, a spring pad vertically adjustable in the body section, end members liinged to said section and independently adjnstablel said section and independently adjustable thereon, braces pivotally mounted upon the end members and adjustably engaged in the body section, whereby the end members may be secured at any desired angle with reference thereto, and means for yieldingly limit-- ing the upward movement of said end members.

3. A bed comprising a frame,'an intermediate body section vertically adjustable therein, a spring pad vertically adjustable in the body section, end members hinged to said section and independently adjustable thereon, braces having spaced notches along their lower edges pivotally secured upon said members and adapted for adjustable engagement in said body section, each of said braces terminating in an irregular curve whereby the end members are permitted to be raised to a vertical position, when the braces will engage in said body section to limit such movement.

4. A bed comprising a frame, an intermediate body section vertically adjustable therein, a spring pad vertically adjustable in the body section, end members hinged to said section and independently adjustable thereon, braces having spaced notches along their lower edges, pivotally mounted on said members and adapted for adjustable engagement in said bodysection, whereby the end sections may be secured at any desired angle with reference to the body section, and means mounted on the body section for holding said braces from engagement therein during the downward movement of the end members. g

In testimon whereof I aiiix my signature in presence 0 two witnesses.
